CMS55v7 - Median Time from ED Arrival to ED Departure for Admitted ED Patients (ED-1)

Rationale:

Median Time from ED Arrival to ED Departure for Admitted ED Patients (ED-1). In recent times, EDs have experienced significant overcrowding. Although once only a problem in large, urban, teaching hospitals, the phenomenon has spread to other suburban and rural healthcare organizations. According to a 2002 national U.S. survey, more than 90% of large hospitals report EDs operating 'at' or 'over' capacity. Approximately one third of hospitals in the US report increases in ambulance diversion in a given year, whereas up to half report crowded conditions in the ED. In a recent national survey, 40% of hospital leaders viewed ED crowding as a symptom of workforce shortages. ED crowding may result in delays in the administration of medication such as antibiotics for pneumonia and has been associated with perceptions of compromised emergency care. For patients with non-ST-segment-elevation myocardial infarction, long ED stays were associated with decreased use of guideline-recommended therapies and a higher risk of recurrent myocardial infarction. Overcrowding and heavy emergency resource demand have led to a number of problems, including ambulance refusals, prolonged patient waiting times, increased suffering for those who wait, rushed and unpleasant treatment environments, and potentially poor patient outcomes. When EDs are overwhelmed, their ability to respond to community emergencies and disasters may be compromised.

Data Elements

EmergencyDepartmentVisitPerformed

Clinical Focus: This set of values identifies procedures representing an emergency department encounter.

Data Element Scope: The intent of this data element is to identify patients who have had an emergency department encounter. Using the Quality Data Model, this particular element will map to the 'Encounter' category.

Inclusion Criteria: Include codes representing an emergency department visit encounter utilizing the SNOMED CT code system.

Exclusion Criteria: None

Subject constrained to the Emergency Department Visit

EncounterPerformed: Data elements that meet criteria using this datatype should document that the encounter indicated by the QDM category and its corresponding value set is in progress or has been completed. Timing: The Relevant Period addresses: startTime – The time the encounter began (admission time) stopTime – The time the encounter ended (discharge time). The Author dateTime addresses when an Encounter is documented. Documentation can occur at the beginning, during, at the end or subsequent to the end of an Encounter. The Author dateTime should be used only if the Relevant Period cannot be obtained. The Location Period is an attribute of the attribute facility location addresses: startTime = the time the patient arrived at the location; stopTime = the time the patient departed from the location

Clinical Focus: This set of values identifies hospital environments where a patient may receive inpatient or outpatient care.

Data Element Scope: The intent of this data element is to identify hospital environments where a patient may receive inpatient or outpatient care. Using the Quality Data Model, this particular element will map to the Transfer category.

Inclusion Criteria: Use the concept of hospital environment (22232009) and all its children. Codes used are to be SNOMED-CT codes only.

Exclusion Criteria: None.

AdmissionSource: The location from which the patient was admitted (e.g., physician referral, facility from which the patient was transferred).

Clinical Focus: This grouping value set identifies diagnoses that are commonly used in the inpatient setting for psychiatric and mental health disorders.

Data Element Scope: The intent of this data element is to identify patients who have an active diagnosis for a psychiatric or mental health disorder. Using the Quality Data Model, this particular element will map to the 'diagnosis' category.

Inclusion Criteria: Include codes representing an active diagnosis for psychiatric and mental health disorders utilizing ICD 10 CM and SNOMED CT codes systems.

Exclusion Criteria: None.

PrincipalDiagnosis: The coded diagnosis/problem established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.
